[0048] The present invention will be further described below with reference to the accompanying drawings:

[0049] This embodiment:

[0050] Please see Figure 1-7 In this embodiment: a purification sample loading auxiliary device includes: a flow component, a blocking structure and a synchronous driving structure.

[0051] In this embodiment, the flow assembly is used for liquid loading; the flow assembly includes: flow tube 1, which can circulate the liquid internally.

[0052] In this embodiment, the flow assembly is used to connect the sample loading machine and the centrifugal purification machine; the top view of the flow tube 1 is rhomboid and the cross-sectional shape is circular; the auxiliary liquid used in the flow assembly for disinfection is an alkaline solution that can be mixed with the virus solution without affecting the virus, and the auxiliary liquid will be separated out during the purification of the virus solution.

[0053] The blocking structure is connected to the flow tube 1 and is used to block the flow tube 1. The blocking structure includes four sets of blocking boxes 4, each set of blocking boxes 4 is set at the cross-sectional position of the flow tube 1 and is connected to the flow tube 1.

[0054] In this embodiment, a portion of the flow pipe 1 can be cut off by a blocking structure to allow air to escape.

[0055] The synchronous drive structure is connected to multiple sets of blocking structures to control the opening and closing of the blocking structures.

[0056] In this embodiment, by operating the synchronous drive structure, the synchronous drive structure can control the opening and closing of the blocking structure, so that part of the flow pipe 1 is cut off, thereby ensuring that the liquid moves in the same direction during the exhaust process, realizing the complete exhaust of gas in multiple pipes at the same time, making the exhaust more thorough and convenient to use.

[0057] like Figure 3 and Figure 4 As shown, the blocking structure also includes: four sets of sealing sleeves 5, four sets of blocking components 6, two sets of second connecting components 15, and two sets of moving components.

[0058] Each sealing sleeve 5 is installed inside the blocking box 4 and is fixedly connected to the inner wall of the blocking box 4.

[0059] In this embodiment, a channel is provided on the surface of the sealing sleeve 5. The shape of this channel is the same as that of the blocking member, and the size of the channel is smaller than that of the blocking member.

[0060] Each set of blocking elements 6 penetrates through the blocking box 4 and extends into the interior of the blocking box 4, and the edge of the blocking element 6 is tightly fitted with the sealing sleeve 5.

[0061] In this embodiment, the flow tube 1 is cut off by fully inserting the blocking member 6 into the blocking box 4 and completely blocking the channel with the blocking member 6.

[0062] One end of each of the two sets of second connectors 15 is fixedly connected to the two sets of opposite blocking members 6.

[0063] In this embodiment, the second connector 15 can drive the connected blocking member 6 to move vertically.

[0064] The two sets of moving components are fixedly connected to the other two sets of blocking components 6.

[0065] In this embodiment, the movable component can cause the blocking component 6 connected to it to move vertically.

[0066] The inner wall of the sealing sleeve 5 has a groove, which allows the blocking member 6 to be inserted into the groove.

[0067] In this embodiment, the sealing sleeve 5 is made of rubber material. After the blocking member 6 is inserted into the groove, it will squeeze the sealing sleeve 5 outward to achieve the sealing effect.

[0068] When blocking is required, by pushing the second connector 15, the two sets of second connectors 15 will drive the two sets of blocking members 6 connected to them to move downward, so that the blocking members 6 are inserted into the groove of the sealing sleeve 5 and squeeze the sealing sleeve 5 outward to achieve a sealing effect and block the flow pipe 1. When the moving component is operated, the moving component will cause the two sets of blocking members 6 connected to it to move vertically to cut off the flow pipe 1, so that the flow pipe 1 maintains a specific flow direction and uses auxiliary liquid to push out the internal air.

[0069] like Figure 5 As shown, each set of moving components includes: a first connecting member 7, a rotating rod 8, a supporting member 9, a moving member 10, and a limiting rod 11.

[0070] Specifically, the bottom end of the first connecting member 7 is fixedly connected to the blocking member 6; a first cylindrical pin is provided on both sides of the first connecting member 7; a first sliding groove and a second sliding groove are respectively opened at both ends of the rotating rod 8, so that the first cylindrical pin is placed in the first sliding groove, and the rotating rod 8 is slidably connected to the first connecting member 7 through the first sliding groove.

[0071] In this embodiment, when the rotating rod 8 rotates, it will use the inclined contact surface between the first sliding groove and the first cylindrical pin to transmit a force biased towards the vertical direction to the first cylindrical pin; this force can be upward or downward, depending on the rotation direction of the rotating rod 8; and since the blocking member 6 can only move vertically under the restriction of the blocking box 4, the first cylindrical pin drives the blocking member 6 to move vertically through the first connecting member 7.

[0072] One end of the support member 9 is rotatably connected to the center of the rotating rod 8.

[0073] In this embodiment, the support member 9 can support the rotation of the rotating rod 8.

[0074] The two sides of the movable part 10 are provided with the second cylindrical pin; the second cylindrical pin is provided in the second slide groove and is slidably connected to the rotating rod 8 through the second slide groove.

[0075] In this embodiment, by vertically moving the movable member 10, the inclined contact surface between the second cylindrical pin and the second sliding groove is used to transmit a force close to the vertical direction to the rotating rod 8; and since there is a certain space between the second cylindrical pin and the second sliding groove, the rotation of the rotating rod 8 is not restricted; thus, the rotating rod 8 rotates under the support of the support member 9.

[0076] One end of the limiting rod 11 extends into the interior of the moving part 10 and is slidably connected to the moving part 10.

[0077] In this embodiment, the sliding between the limiting rod 11 and the moving member 10 restricts the moving member 10 to move only vertically.

[0078] By making the moving part 10 move vertically, the moving part 10 will slide between the second cylindrical pin and the second slide groove, causing the rotating rod 8 to rotate. The rotating rod 8 will slide between the first slide groove and the first cylindrical pin, causing the first cylindrical pin to drive the first connecting part 7 to move in the opposite direction to the moving part 10. The first connecting part 7 will simultaneously drive the blocking part 6 connected to it to move, thereby achieving blocking.

[0079] The purification and sample loading auxiliary device also includes: a support plate 18, the upper end of which is fixedly connected to the other end of the support member 9; and the surface of the support plate 18 is fixedly connected to four sets of blocking boxes 4.

[0080] In this embodiment, the stability of the blocking box 4 and the flow tube 1 can be improved by the support plate 18.

[0081] like Figure 2 and Figure 3 As shown, the synchronous drive structure includes: a moving block 13, two sets of first moving rods 12, two sets of second moving rods 14, a threaded rod 16, and a handwheel 17.

[0082] The movable block 13 is positioned directly above the support plate 18; one end of each set of first movable rods 12 is fixedly connected to the movable block 13; the other end of the first movable rod 12 is provided with a first through hole, allowing the movable component 10 to pass through the first through hole, and allowing the first movable rod 12 to slide in connection with the movable component 10 through the first through hole.

[0083] In this embodiment, the moving block 13 can drive the first moving rod 12 to move synchronously; when the first moving rod 12 moves, it can slide along the outside of the moving member 10; and after the moving member 10 and the first moving rod 12 are fixed, the first moving rod 12 will drive the moving member 10 to move synchronously.

[0084] One end of each set of second moving rods 14 is fixedly connected to the moving block 13; the other end of the second moving rod 14 is provided with a second through hole, so that the second connecting piece 15 passes through the second through hole, and the second moving rod 14 is slidably connected to the second connecting piece 15 through the second through hole.

[0085] In this embodiment, the moving block 13 can simultaneously drive the second moving rod 14 to move vertically; when the second moving rod 14 and the second connecting member 15 are not fixed, the second moving rod 14 can slide along the outer wall of the second connecting member 15; and when the second moving rod 14 and the second connecting member 15 are fixed, the second moving rod 14 can drive the second connecting member 15 to move vertically at the same time.

[0086] One end of the threaded rod 16 passes through the movable block 13 and is threadedly connected to the movable block 13; the other end of the threaded rod 16 passes through the support plate 18 and is rotatably connected to the support plate 18; the center of the handwheel 17 is fixedly connected to the end of the threaded rod 16 near the support plate 18.

[0087] In this embodiment, by rotating the handwheel 17, the threaded rod 16 can be rotated, and the threaded rod 16 will cause the moving block 13 to move vertically.

[0088] When the blocking structure needs to be driven, the user can turn the handwheel 17, which will drive the threaded rod 16 to rotate. The threaded rod 16 will cause the moving block 13 to move vertically. The moving block 13 will simultaneously drive the first moving rod 12 and the second moving rod 14 to move. The blocking structure is driven to operate by the first moving rod 12 and the second moving rod 14. Since the two sets of first moving rods 12 and the two sets of second moving rods 14 move at the same time, multiple blocking structures can operate at the same time.

[0089] Each set of first moving rods 12 and each set of second moving rods 14 have two sets of notches on their surfaces, and the two sets of notches are located on the same vertical line.

[0090] In this embodiment, the first moving rod 12 and the moving part 10, and the second moving rod 14 and the second connecting part 15 are fixed together by the cooperation of the notch and the locking component.

[0091] The purification and sample loading auxiliary device also includes: multiple sets of locking components; each set of locking components is connected to the synchronous drive structure and the blocking structure, and is used to fix the synchronous drive structure and the blocking structure together.

[0092] like Figure 6 and Figure 7 As shown, each locking component includes: a support frame 19, a through-hole insert 20, a limiting plate 21, and an elastic element 22.

[0093] Specifically, the support frame 19 is fixedly connected to the synchronous drive structure.

[0094] In this embodiment, multiple sets of support frames 19 are fixed to two sets of first moving rods 12 and two sets of second moving rods 14, respectively.

[0095] The insert 20 consists of a handle and a pin. One end of the pin is fixedly connected to the handle; the other end of the pin passes through the support frame 19 and is slidably connected to the support frame 19, and extends into a set of notches.

[0096] In this embodiment, the fixing is achieved by inserting the insert 20 into the notch; and the fixing position is changed by using different notch positions.

[0097] The limiting plate 21 is fitted onto the pin and is fixedly connected to the pin.

[0098] In this embodiment, the limiting plate 21 can limit the depth of the pin insertion into the notch.

[0099] The elastic element 22 is disposed between the limiting plate 21 and the support frame 19 and is sleeved on the pin.

[0100] In this embodiment, the elastic element 22 is currently in a compressed state. When the limiting plate 21 moves away from the notch, the elastic element 22 will be compressed again.

[0101] When the fixed position needs to be changed, first pull the insert 20 outward to disengage it from the notch and move the limiting plate 21. The limiting plate 21 and the support frame 19 work together to compress the elastic element 22 again. At this time, the movement of the synchronous drive structure will not cause the connected blocking structure to move. When the insert 20 moves to another set of notch positions, release the insert 20. At this time, the elastic element 22 rebounds, allowing the insert 20 to be inserted into the corresponding notch, and fixing the synchronous drive structure and the blocking structure together again, so that the synchronous drive structure can make the blocking structure operate. By changing the fixed position, the order of operation of the blocking structure is changed, so that no air is generated in the flow pipe 1 when the blocking structure is operating.

[0102] like Figure 1 As shown, the flow assembly also includes: four sets of telescopic pipes 2 and four sets of pipe interfaces 3.

[0103] Each set of telescopic pipes 2 is located between two sets of blocking boxes 4, and one end of the telescopic pipe 2 is connected to the flow pipe 1.

[0104] In this embodiment, the telescopic tube 2 can be extended and compressed, but the distance of extension and compression is limited.

[0105] Each set of pipe interfaces 3 is located at the other end of the telescopic pipe 2 and is fixedly connected to the telescopic pipe 2.

[0106] In this embodiment, the four sets of pipe interfaces 3 are respectively connected to the liquid outlet of the sample loading device, the liquid inlet of the centrifugal purifier, the liquid outlet of the centrifugal purifier, and the liquid inlet of the waste liquid container. The sample loading device sends auxiliary liquid to the flow pipe 1 through the first set of pipe interfaces 3, so that the liquid flows from the second set of pipe interfaces 3 to the centrifugal purifier, and pushes the air in the centrifugal purifier into the flow pipe 1 through the third set of pipe interfaces 3, and sends it to the waste liquid container from the fourth set of pipe interfaces 3 to realize the venting process. The blocking structure can control the flow direction of the liquid, ensuring that the liquid flows from the second set of pipe interfaces 3 through the centrifugal purifier back to the flow pipe 1, and preventing the liquid from flowing into the centrifugal purifier from the second set of pipe interfaces 3 and the third set of pipe interfaces 3 at the same time, so as to expel the air.

[0107] Working principle:

[0108] When in use, the purification and sample loading auxiliary device connects four sets of pipe interfaces 3 to the liquid outlet of the sample loading device, the liquid inlet of the centrifugal purifier, the liquid outlet of the centrifugal purifier, and the liquid inlet of the waste liquid container, respectively. Subsequently, the sample loading device sends the auxiliary liquid to the flow pipe 1 through the first set of pipe interfaces 3, so that the liquid flows from the second set of pipe interfaces 3 into the centrifugal purifier, and pushes the air in the centrifugal purifier into the flow pipe 1 through the third set of pipe interfaces 3, and sends it to the waste liquid container from the fourth set of pipe interfaces 3 to realize the exhaust process.

[0109] The blocking structure can control the flow direction of the liquid. By pushing the second connector 15, the two sets of second connectors 15 will drive the two sets of blocking members 6 connected to them to move downward, so that the blocking members 6 are inserted into the groove of the sealing sleeve 5 and squeeze the sealing sleeve 5 outward to achieve a sealing effect and block the flow pipe 1. When the moving component is operated, the moving component will cause the two sets of blocking members 6 connected to it to move vertically to cut off the flow pipe 1, ensuring that the liquid flows from the second set of pipe interfaces 3 through the centrifugal purifier back to the flow pipe 1, preventing the liquid from flowing into the centrifugal purifier from the second set of pipe interfaces 3 and the third set of pipe interfaces 3 at the same time, and can discharge air; at the same time, the entire flow component and the centrifugal purifier are disinfected.

[0110] When the moving component is in operation, by making the moving part 10 move vertically, the moving part 10 will slide between the second cylindrical pin and the second slide groove, causing the rotating rod 8 to rotate. The rotating rod 8 will slide between the first slide groove and the first cylindrical pin, causing the first cylindrical pin to drive the first connecting part 7 to move in the opposite direction to the moving part 10. The first connecting part 7 simultaneously drives the blocking part 6 connected to it to move, thereby achieving blocking.

[0111] When the blocking structure needs to be driven, the user can turn the handwheel 17, which will drive the threaded rod 16 to rotate. The threaded rod 16 will cause the moving block 13 to move vertically. The moving block 13 will simultaneously drive the first moving rod 12 and the second moving rod 14 to move. The blocking structure is driven to operate through the first moving rod 12 and the second moving rod 14. Since the two sets of first moving rods 12 and the two sets of second moving rods 14 move at the same time, multiple blocking structures can operate at the same time.

[0112] When the fixed position needs to be changed, first pull the insert 20 outward to disengage it from the notch and move the limiting plate 21. The limiting plate 21 and the support frame 19 work together to compress the elastic element 22 again. At this time, the movement of the synchronous drive structure will not cause the blocking structure connected to it to move. When the insert 20 moves to another set of notch positions, release the insert 20. At this time, the elastic element 22 rebounds, allowing the insert 20 to be inserted into the corresponding notch, and the synchronous drive structure and the blocking structure are fixed together again, so that the synchronous drive structure can make the blocking structure operate. By changing the fixed position, the order of operation of the blocking structure is changed, so that the operation time of the blocking structure connected to the first moving rod 12 and the second moving rod 14 is staggered. That is, the blocking structure connected to the first moving rod 12 cuts off the flow tube 1 first, and the blocking structure connected to the second moving rod 14 opens the flow tube 1. So that no air is generated in the flow tube 1 when the blocking structure is operating, thus completing the use of this device.
